某电厂凝汽器铜管渗漏原因分析

文章通过对某火力发电厂#2机组凝汽器铜管频繁腐蚀泄漏的现状、泄漏形成的原因进行分析,确认氨腐蚀为凝汽器铜管泄漏的根本原因;同时根据其腐蚀特征及腐蚀分布情况,采取了有效措施,防止了铜管的进一步腐蚀,确保了凝汽器良好的换热效率和凝结水水质。

Based on the analysis of the present situation of frequent corrosion leakage of condenser copper tube of#2 unit in a thermal power plant and the causes of leakage,it is confirmed that ammonia corrosion is the fundamental cause of condenser copper tube leakage.At the same time,according to its corrosion characteristics and corrosion distribution,effective measures are taken to prevent further corrosion of copper tube and ensure good heat transfer efficiency and condensate water quality of condenser.
